Green invaders are taking over America. Not invaders from space, but plants! You might not think of plants as dangerous, but in this case they are threatening nature’s delicate food chain.
The invaders are plants brought here from other countries to make gardens and yards look pretty. Ever since people started to arrive on America’s shores, they have carried along trees, flowers, and vegetables from other places. Now there are so many of those plants, they are crowding out the native plants that have lived here since before human settlers arrived.
And that’s a problem, says Dr. Doug Tallamy. He’s insect expert at the University of Delaware. He explains that almost all the plant-eating insects in the United States are specialized, which means they eat only certain plants. Monarch butterfly caterpillars(幼虫),for example, dine on milkweed. If people cut down milkweed and replace it with another plant, the butterflies will not have the food source that they need to survive.
But the trouble doesn’t stop there. When insects can’t get the right plants to eat and they die off, then the birds don’t have enough bugs for their meals. Tallamy points out that almost all migrating birds depend on insets to feed their young.
“We cannot let the plants and animals around us disappear.” says Tallamy, “The way to preserve them is to give them food to eat. But when we plant non-native plants, we are clobbering the food chain, because then we don’t have the insects the birds need to live.”
Fewer of the right plants mean fewer bugs, and fewer bugs mean fewer birds. And that’s bad for the Earth, because we need a variety of living things to keep the planet healthy and beautiful.
The good news is, garden centers sell native plants. “Just Google ‘native plants’ and your location, and you can find out which plants really belong where you live,” says TallamyHow did green invades arrive at America?
| A．They fell down from space. |
| B．They floated to the America’s shores. |
| C．They were brought in from foreign countries |
| D．They has lived here since human settlers arrived |
According to Dr.Tallamy, which of the followings about the insects in the US is NOT true?
| A．Almost all the plant-eating insects in a place eat certain plants. |
| B．Monarch butterfly caterpillars can’t survive without milkweed. |
| C．If insects can’t eat the right plants, they will find another one. |
| D．The insects’ death will greatly affect the migrating birds’ survival |

| A．protect | B．damage | C．create | D．collect |
We can know whether a plant is native by _________.
| A．Googling on the Internet | B．asking Dr. Doug Tallamy |
| C．looking up in books | D．searching in garden |
What is the best title of the pass age?
| A．Green invaders——local living things |
| B．Green invaders——dangerous food chain |
| C．Green invaders——environmental protectors |
| D．Green invades——threat to local nature |
The best way to improve your reading ability is, of course, to read. The student must make a real effort to improve his speed, and if necessary his comprehension, with each exercise. Too many students read passages passively（被动的） and without judgment: they simply start at the first word and read through to the end. You should read a passage actively, selectively（选择地） and purposely. You must believe that you indeed have the ability to read faster and understand, and that you will.
Reading, like everything else in life, is best done when you’re relaxed. The key to improve it is concentration. You must be willing to break some old habits and form new ones. Extra body movement, such as turning the head from side to side, pointing at the line with a finger or pencil, or moving the lips, should be stopped immediately. Reading is mostly a mental process(大脑活动过程) and body movement helps neither speed nor comprehension. Then you should see words as part of a whole sentence or paragraph, not just in isolation(孤立), This is why a slow, word-by-word student often understands far less, or misses much of the joy and excitement of reading.
The student must learn to improve reading skills on their own, and not just when a teacher is looking over his shoulder. Reading improvement takes discipline（纪律） and effort. Don’t give up.

4. The best title for this passage is___________.

A holiday is any day when people lay aside their ordinary duties and cares. The word comes from Old English. At first, holidays honored some holy(神的) events or persons. People in Great Britain and other countries speak of holidays as Americans speak of vacations.

China observes New Year’s Day(January 1), May Day and National Day as legal(法定的) holidays, as it was on Oct. 1, 1949 that People’s Republic of China was founded. The Chinese have long celebrated the Chinese lunar year. In the United States, congress（国会） has declared(宣告) several as legal days such as New Year's Day (January1), Martin Luther King, Jr.’s Birthday, Washington's Birthday, Thanksgiving Day and Christmas Day and so on. Some holidays celebrate special events in the development of a country, such as Greece’s Independence Day, Italy’s Liberation Day and India’s Independence Day.
